Analysis of superconducting magnet (SCM)-ground coil interactions for EDS Maglev coil configurations

The performance of electrodynamic magnetic levitation systems is dominated primarily by the electromagnetic interactions between the onboard superconducting magnets (SCMs) and the normal levitation and propulsion coils situated on the guideway. Alternative designs are examined for coil configurations in terms of the resulting SCM-ground coil interactions. In particular, the modified null flux configuration and the ladder-on-box-beam approach are compared. Magnetic drag, levitation, and guidance forces are considered on an absolute and per (kg/m) of ground coil basis.<>
